The most interesting case is emails with Cc headers coming from an address with a domain for which strict DMARC settings are configured (in which case the 'From' will be rewritten to 'John Doe via dev@beam.apache.org' and the original sender moved to the Cc). Of course we have tested that specific scenario already on our dummy lists, so we're pretty confident that it works - the 'guinea pig' test is mostly to discover if there's any unexpected changes in behaviour we didn't foresee.
